Notification of event subsequent to communication failure with security system

ABSTRACT

Methods and systems for monitoring a premises are described. A server external to the premises may be in communication with a system at the premises. The server may receive status data from the system from one or more interfaces. If a loss of communication occurs on one interface, then the status data may be received via a second interface. The server may determine timing information for status data received via the first interface and for status data received via the second interface. The server may send, based on the timing information, a message to a computing device indicating the loss of communication.

FIELD OF THE INVENTION

Embodiments of the present invention relate generally to the field ofhome security, monitoring and automation, and specifically to remotelyproviding zone fault event notification to one or more of a user of ahome security, monitoring and automation device and a security centralstation in the event of a loss of communication with the home security,monitoring and automation device.

BACKGROUND OF THE INVENTION

Residential electronics and control standards provide an opportunity fora variety of options for securing, monitoring, and automatingresidences. Wireless protocols for transmission of security informationpermit placement of a multitude of security sensors throughout aresidence without a need for running wires back to a central controlpanel.

Inexpensive wireless cameras also allow for placement of camerasthroughout a residence to enable easy monitoring of the residence. Avariety of home automation control protocols have also been developed toallow for centralized remote control of lights, appliances, andenvironmental apparatuses (e.g., thermostats). Traditionally, each ofthese security, monitoring and automation protocols require separateprogramming, control and monitoring stations. To the extent that homeautomation and monitoring systems have been coupled to home securitysystems, such coupling has involved including the automation andmonitoring systems as slaves to the existing home security system. Thislimits the flexibility and versatility of the automation and monitoringsystems and ties such systems to proprietary architectures.

A security system alerts occupants of a dwelling and emergencyauthorities of a violation of premises secured by the system. A homemonitoring system monitors a status of a home so that a user can be madeaware of any monitored state changes. A home automation system automatesand remotely controls lifestyle conveniences such as lighting, heating,cooling, and appliances.

Rather than having multiple devices to control each of the security,monitoring and automation environments, it is desirable to have acentralized controller capable of operating in each environment, therebyreducing the equipment needed in a dwelling. It is further desirable forsuch a controller to function as a gateway for external network access.Gateway access can include user access to the controller in order tocontrol or monitor devices in locations remote from the dwelling.

A single controller controlling security, monitoring and automation canbecome a point source for failure, either accidentally or by design(e.g., an intruder disabling the device). It is therefore desirable tohave a mechanism for reporting a loss of communication with thecontroller to an end user or selected others. It is further desirable tohave a mechanism to report a zone fault event to a central station andan end user in the event communication with the controller is lostsubsequent to the zone fault event and one or more delay timers haveexpired.

SUMMARY OF THE INVENTION

Systems and methods for server-based notifications of alarm eventssubsequent to a communication failure with an armed security system aredescribed. An example system may comprise a security, monitoring, andautomation (SMA) system and a server. The SMA system may comprise aplurality of components and may be configured to monitor the premises atwhich the SMA system is located. The server may be located external tothe premises. The server may be in communication with first and secondcomponents of the SMA system via first and second network connections,respectively. The server may be configured to receive first status datafrom the first component and via the first network connection. Theserver may determine a loss of communication, via the first networkconnection, between the server and the first component. In response, theserver may receive second status data from the second component and viathe second connection. Based on the time of receiving the first statusdata and the time of receiving the second status data, the server maysend a message that indicates the first status data.

In an example method, a server may receive, via a first networkconnection, first status data from a first component of a security,monitoring, and automation (SMA) system. The SMA system may be locatedat a premises and may monitor that premises. The server may be locatedexternal the premises. A loss of communication, via the first networkconnection, between the server and the first component may bedetermined. In response, the server may receive second status data froma second component of the SMA system and via a second networkconnection. Based on the time of receiving the first status data and thetime of receiving the second status data, a message may be sent to aremote computing device.

An example system may comprise a security, monitoring, and automation(SMA) system and a server.

DETAILED DESCRIPTION

Embodiments of the present invention provide a server-based environmentfor reporting a status of a security, monitoring and automation (SMA)controller. Embodiments of the present invention provide for detectingcessation of an always-on persistent network connection between the SMAcontroller and a remote server. An aspect of these embodiments furtherprovides for reporting the cessation of the network connection to an enduser and defined others. A further aspect provides for automaticallyreporting an alarm event to a central station, the end user, or others,in the event the cessation of the network connection occurs while theSMA controller is armed and after a sensor zone fault event, and notreceiving a disarm notification prior to expiration of a preset entrydelay.

Architectural Overview

Embodiments of the configurable security, monitoring and automation(SMA) controller of the present invention provide not only forcommunicating with and interpreting signals from sensors and deviceswithin a dwelling, but also for accessing and monitoring those sensorsand devices from locations remote to the dwelling. Embodiments of theSMA controller provide such capability through linkages to externalservers via access networks such as the Internet, provider network, or acellular network. The external servers provide a portal environmentthrough which a user can, for example, monitor the state of sensorscoupled to the SMA controller in real-time, configure the controller,and provide controlling information to the SMA controller. The externalservers can also monitor the state of the SMA controller and the networkconnections between the SMA controller and the servers. The serversfurther provide a connection to a traditional security central station,which can then contact authorities in the event of an alarm conditionbeing detected by the SMA controller in the dwelling.

FIG. 1A is a simplified block diagram illustrating an architectureincluding a set of logical domains and functional entities within whichembodiments of the present invention interact. A home domain 110includes an embodiment of the SMA controller 120. The home domain iscoupled via an access domain 150 to an operator domain 160 that includesvarious servers. The servers are in turn coupled to a central station190 and to various remote user communication options.

The home domain refers to a collection of security, monitoring andautomation entities within a dwelling or other location having SMAdevices. SMA controller 120 is a device that provides an end-user SMAinterface to the various SMA entities (e.g., radio-frequency sensors)within home domain 110. SMA controller 120 further acts as a gatewayinterface between home domain 110 and operator domain 160. SMA gateway120 provides such gateway access to operator domain 160 via a networkrouter 125. Network router 125 can be coupled to SMA controller 120 andto home network devices such as home computer 127 via either hard wiredor wireless connections (e.g., WiFi, tethered Ethernet, and power-linenetwork). A network router 125 coupled to a broadband modem (e.g., acable modem or DSL modem) serves as one link to networks in accessdomain 150.

SMA devices within home domain 110 can include a variety of RF orwireless sensors 130 whose signals are received and interpreted by SMAgateway 120. RF sensors 130 can include, for example, door or windowsensors, motion detectors, smoke detectors, glass break detectors,inertial detectors, water detectors, carbon dioxide detectors, and keyfob devices. SMA gateway 120 can be configured to react to a change instate of any of these detectors. In addition to acting and reacting tochanges in state of RF sensors 130, SMA controller 120 also can becoupled to a legacy security system 135. SMA controller 120 controls thelegacy security system by interpreting signals from sensors coupled tothe legacy security system and reacting in a user-configured manner. SMAgateway 120, for example, will provide alarm or sensor state informationfrom legacy security system 135 to servers in operator domain 160 thatmay ultimately inform central station 190 to take appropriate action.

SMA gateway 120 can also be coupled to one or more monitoring devices140. Monitoring devices 140 can include, for example, still and videocameras that provide images that are viewable on a screen of SMA gateway120 or a remotely connected device. Monitoring devices 140 can becoupled to SMA gateway 120 either wirelessly (e.g., WiFi via router 125)or other connections.

Home automation devices 145 (e.g., home area network devices having anautomation interface) can also be coupled to and controlled by SMAgateway 120. SMA gateway 120 can be configured to interact with avariety of home automation protocols, such as, for example, Z-Wave andZigBee.

Embodiments of SMA controller 120 can be configured to communicate witha variety of RF or wireless sensors and are not limited to the RFsensors, monitoring devices and home automation devices discussed above.A person of ordinary skill in the art will appreciate that embodimentsof the present invention are not limited to or by the above-discusseddevices and sensors, and can be applied to other areas and devices.

Embodiments of SMA controller 120 can be used to configure and controlhome security devices (e.g., 130 and 135), monitoring devices 140 andautomation devices 145, either directly or by providing a gateway toremote control via servers in operator domain 160. SMA controller 120communicates with servers residing in operator domain 160 via networksin access domain 150. Broadband communication can be provided bycoupling SMA controller 120 with a network router 125, which in turn iscoupled to a wide area network 152, such as a provider network or theInternet, via an appropriate broadband modem. The router can be coupledto the wide area network through cable broadband, DSL, and the like.Wide area network 152, in turn, is coupled to servers in operator domain160 via an appropriate series of routers and firewalls (not shown). SMAcontroller 120 can include additional mechanisms to provide acommunication with the operator domain. For example, SMA controller 120can be configured with a cellular network transceiver that permitscommunication with a cellular network 154. In turn, cellular network 154can provide access via routers and firewalls to servers in operatordomain 160. Embodiments of SMA controller 120 are not limited toproviding gateway functionality via cellular and dwelling-based routersand modems. For example, SMA gateway 120 can be configured with othernetwork protocol controllers such as WiMAX satellite-based broadband,direct telephone coupling, and the like.

Operator domain 160 refers to a logical collection of SMA servers andother operator systems in an operator's network that provide end-userinterfaces, such as portals accessible to subscribers of the SMAservice, that can configure, manage and control SMA elements within homedomain 110. Servers can also provide management portals for the providerto configure available services to the SMA controllers. Servers inoperator domain 160 can be maintained by a provider (operator) ofsubscriber-based services for SMA operations. Examples of providersinclude cable providers, telecommunications providers, and the like. Aproduction server architecture in operator domain 160 can support SMAsystems in millions of home domains 110.

Individual server architectures can be of a variety of types, and in oneembodiment, the server architecture is a tiered Java2 Enterprise Edition(J2EE) service oriented architecture. Such a tiered service orientedarchitecture can include an interface tier, a service tier, and a dataaccess logic tier. The interface tier can provide entry points fromoutside the server processes, including, for example, browser webapplications, mobile web applications, web services, HTML, XHTML, SOAP,and the like. A service tier can provide a variety of selectablefunctionality passed along by the operator to the end user, includingwidget programs. Service tiers can relate to end user subscriptionlevels offered by the operator (e.g., payment tiers corresponding to“gold” level service, “silver” level service and “bronze” levelservice). Finally the data access logic tier provides access to varioussources of data including database servers.

FIG. 1A illustrates an example set of servers that can be provided inoperator domain 160. Servers 165 can support all non-alarm and alarmevents, heartbeat, and command traffic between the various servers andSMA controllers 120. Servers 165 can also manage end-user electronicmail and SMS notification, as well as integration with provider billing,provisioning, inventory, tech support systems, and the like.

A portal server 170 can provide various user interface applications,including, for example, a subscriber portal, a mobile portal, and amanagement portal. A subscriber portal is an end-user accessibleapplication that permits an end-user to access a corresponding SMAcontroller remotely via standard web-based applications. Using such asubscriber portal can provide access to the same SMA functions that aninterface directly coupled to the SMA controller would provide, plusadditional functions such as alert and contact management, historicaldata, widget and camera management, account management, and the like. Amobile portal can provide all or part of the access available to anend-user via the subscriber portal. A mobile portal can be limited,however, to capabilities of an accessing mobile device (e.g., touchscreen or non-touch screen cellular phones). A management portalprovides an operator representative access to support and manage SMAcontrollers in home domains 110 and corresponding user accounts via aweb-based application. Using a management portal, an operatorrepresentative can provision and provide a variety of functionality via,for example, widget programs to the SMA controllers, as will bediscussed in greater detail below. The management portal can providetiers of management support so that levels of access to user informationcan be restricted based on authorization of a particular employee.

Telephony server 180 can process and send information related to alarmevents received from SMA controllers 120 to alarm receivers at centralmonitoring station 190. A server 165 that processes the alarm eventmakes a request to telephony server 180 to dial the central station'sreceiver and send corresponding contact information. Telephony server180 can communicate with a plurality of central stations 190. Server 165can determine a correct central station to contact based upon useraccount settings associated with the transmitting SMA controller. Thus,alarms can be routed to different central stations based upon useraccounts. Further, accounts can be transferred from one central stationto another by modifying user account information. Telephony server 180can communicate with alarm receivers at central station 190 using, forexample, a security industry standard contact identification protocol(e.g., dual-tone multi-frequency [DTMF]) and broadband protocols.

A backup server 175 can be provided to guarantee that an alarm path isavailable in an event that one or more servers 165 become unavailable orinaccessible. A backup server 175 can be co-located to the physicallocation of servers 165 to address scenarios in which one or more of theservers fail. Alternatively, a backup server 175 can be placed in alocation remote from servers 165 in order to address situations in whicha network failure or a power failure causes one or more of servers 165to become unavailable. SMA controllers 120 can be configured to transmitalarm events to a backup server 175 if the SMA controller cannotsuccessfully send such events to servers 165.

A database server 185 provides storage of all configuration and userinformation accessible to other servers within operator domain 160.Selection of a type of database provided by database server 185 can bedependent upon a variety of criteria, including, for example,scalability and availability of data. One embodiment of the presentinvention uses database services provided by an ORACLE database.

FIG. 1B is a simplified block diagram illustrating a logicalarchitecture for a server 165, usable by embodiments of the presentinvention. A server 165 in operator domain 160 provides a variety offunctionality. Logically, a server 165 can be divided into the followingfunctional modules: a broadband communication module 165A, a cellularcommunication module 165B, a notification module 165C, a telephonycommunication module 165D, and an integration module 165E.

Broadband communication module 165A manages broadband connections andmessage traffic from a plurality of SMA controllers 110 coupled toserver 165. Embodiments of the present invention provide for thebroadband channel to be a primary communication channel between an SMAcontroller 120 and servers 165. The broadband communication modulehandles a variety of communication, including, for example, allnon-alarm and alarm events, broadband heartbeat, and command of trafficbetween server 165 and SMA controller 120 over the broadband channel.Embodiments of the present invention provide for an always-on persistentTCP socket connection to be maintained between each SMA controller andserver 165. A variety of protocols can be used for communicationsbetween server 165 and SMA controller 120 (e.g., XML over TCP, and thelike). Such communication can be secured using standard transport layersecurity (TLS) technologies. Through the use of an always-on socketconnection, servers 165 can provide near real-time communication betweenthe server and an SMA controller 120. For example, if a user has asubscriber portal active and a zone is tripped within home domain 110, azone fault will be reflected in near real-time on the subscriber portaluser interface.

Cellular communication module 165B manages cellular connections andmessage traffic from SMA controllers 120 to a server 165. Embodiments ofthe present invention use the cellular channel as a backup communicationchannel to the broadband channel. Thus, if a broadband channel becomesunavailable, communication between an SMA controller and a serverswitches to the cellular channel. At this time, the cellularcommunication module on the server handles all non-alarm and alarmevents, and command traffic from an SMA controller. When a broadbandchannel is active, heartbeat messages can be sent periodically on thecellular channel in order to monitor the cellular channel. When acellular protocol communication stack is being used, a TCP socketconnection can be established between the SMA controller and server toensure reliable message delivery for critical messages (e.g., alarmevents and commands). Once critical messages have been exchanged, theTCP connection can be shut down thereby reducing cellular communicationcosts. As with broadband communication, XMPP can be the messagingprotocol used for such communications. Similarly, such communication canbe secured using TLS and SASL authentication protocols. Non-criticalmessages between an SMA controller and a server can be sent using UDP. Acompressed binary protocol can be used as a messaging protocol for suchcommunications in order to minimize cellular costs for such messagetraffic. Such messages can be secured using an encryption algorithm,such as the tiny encryption algorithm (TEA). Cellular communication canbe established over two network segments: the GSM service provider'snetwork that provides a path between an SMA controller and a cellularaccess point, and a VPN tunnel between the access point and an operatordomain data center.

A notification module 165C determines if and how a user should benotified of events generated by their corresponding SMA controller 120.A user can specify who to notify of particular events or event types andhow to notify the user (e.g., telephone call, electronic mail, textmessage, page, and the like), and this information is stored by adatabase server 185. When events such as alarm or non-alarm events arereceived by a server 165, those events can be passed asynchronously tothe notification module, which determines if, who and how to send thosenotifications based upon the user's configuration.

As discussed above, the network connection between an SMA controller 120and a server 165 is always on and persistent. This allows for constantremote monitoring of the state of the SMA controller, sensors, anddevices coupled to the SMA controller. Notification module 165C can beconfigured to report state changes of the SMA controller and sensors topreviously determined entities. Such state change information can alsoinclude a current communication mode between the SMA controller andserver. For example, if broadband communication becomes unavailable anda switch is made to cellular communication, an end user can beautomatically notified of the change. Likewise, if all communicationwith the SMA controller is lost, then a different notification can beprovided. The nature of a notification associated with an event can beconfigured by an end user or provider through portal server 170 or aninput device coupled to SMA controller 120.

Connectivity reporting can also be used to report a loss ofcommunication subsequent to a zone fault event and to define a responseto such a scenario. An SMA controller can be configured with an entrydelay timer that allows a person entering home domain 110, and therebytriggering a zone fault event, to disarm an armed SMA controller beforean alarm signal is sent to a central station 190. An intruder to thehome domain might take advantage of the unified nature of the SMAcontroller and disable the SMA controller prior to expiration of theentry delay (i.e., a so-called “smash-and-grab” scenario), in order toprevent sounding of an alarm. The continuous communication between theSMA controller and an operator domain server results in the sensor statechange associated with the zone fault event to be provided to a server165 in near real time, along with a message indicating that the SMAcontroller's entry delay timer has been initiated. If the serversubsequently detects a loss of communication with the SMA controllerbefore a disarm signal is received, the notification module can beconfigured to relay an alarm signal to, for example, one or more of theend user, the central station, and a provider administrator. The alarmsignal can be defined using available central station protocols (e.g.,contact ID) to indicate a “smash and grab” scenario or an indicationthat is agreed upon between the central station provider and theprovider of the operator domain services.

The server can further be configured with a delay window that results inthe server waiting to report an alarm associated with the zone faultevent. This allows for communication to be restored with the SMAcontroller and a disarm signal to be received prior to transmission ofthe alarm report. A configurable server delay window can be defined inaccord with security industry best practices, such as those defined inANSI/SIA CP-01-20xx (Revision of ANSI/SIA CP-01-2007) “Control PanelStandard—Features for False Alarm Reduction” (e.g., a combination of oneor more of the standard's entry delay, abort window and cancel window).Alternatively, the configurable server delay window can be defined inaccord with a provider's specifications (e.g., customer tiers orpurchased services). The delay window timer can be started at the sametime the message indicating that the SMA controller's entry delay timerhas been initiated is received. Alternatively, the server can start thedelay window timer at the same time the loss of communication isdetected. As a further alternative, the server can independently trackthe entry delay timer when the message indicating that the SMAcontroller's entry delay timer has been initiated and then start thedelay window time subsequent to the expiration of the entry delay timer.In general, a delay window timer tracked by the server can include anaggregation of the entry delay timer, as configured at the SMAcontroller, and an additional time configured by the provider (e.g., a“smash and grab” wait time). This general delay window timer can bestarted at the time the message indicating that the SMA controller'sentry delay timer has been initiated is received (or alternatively, uponreceipt of the zone fault event message while the system state isarmed).

FIG. 2 is a simplified flow diagram illustrating reporting of loss ofconnectivity and possible transmission of an alarm associated with azone fault event, in accord with embodiments of the present invention.As discussed above, state information related to the SMA controller isreceived by a server 165 using, for example, a persistent networkconnection through a broadband communication module 165A (210). Suchstate information can include, for example, an indication of continuedoperation of the SMA controller, arm/disarm, and sensor event statechanges (e.g., a zone fault event).

The server then detects a loss of connectivity or communication with theSMA controller (220). If the server determines that the SMA controllerwas not armed (230), then a notification of the loss of communication istransmitted by notification module 165C to preconfigured recipients(e.g., the end users) (240). If the server determines that the SMAcontroller was armed at the time of loss of communication (230), adetermination can be made as to whether a sensor zone fault event hadbeen detected prior to the loss of communication (250). If no sensorevent had been detected, then a notification of loss of communicationcan be transmitted to the preconfigured recipients (240). If a sensorevent had been detected prior to the loss of communication, and thesystem was armed, then a determination is made as to whether thepreconfigured server delay window has expired (260). The delay window istracked solely by the server, but can include an aggregation of theentry delay configured by the SMA controller as well as an additionaltime configured by the provider (e.g., the “smash and grab” wait time).The delay window timer can begin at the time a message is received bythe server that an entry delay timer has been initiated or at the timethe loss of connectivity is detected.

If the delay window has not expired, then a determination is made as towhether communication is restored and the SMA controller is disarmed(270). If communications are restored and the SMA controller isdisarmed, then the process can return to a monitoring state (210). Ifcommunications are not restored and the SMA controller disarmed, thencommunications are monitored until the expiration of the delay window.Once the delay window expires without further communication with the SMAcontroller, an alarm event message is transmitted to a central station190 and to other preconfigured recipients (280). As discussed above, thealarm event message can be designated as a “smash and grab” alarm eventor a general alarm event, as agreed to between the central stationprovider and the provider of SMA services.

As indicated above, the server-based delay window is configurable by theprovider of the SMA services. In one embodiment, the server-based delaywindow can represent an aggregate of the user-configurable entry delayon the SMA controller and a provider-configurable “smash and grab” delaytime (e.g., entry delay of 30 seconds and a “smash and grab” delay timeof 60 seconds results in a total delay window of 90 seconds beforesending the alarm message to the central station). In anotherembodiment, an SMA controller can be configured to send an alarmindication message to the remote server, but then the server will waitthe delay window time to receive a second alarm message or a cancelmessage from the SMA controller before sending the alarm message to thecentral station. In this embodiment, the server can wait for the delaywindow to expire before sending the alarm if the server hasn't receivedthe second message from the SMA controller. If a second alarm message isreceived, then an alarm message will be sent to the central stationimmediately, without waiting for expiration of the delay window. In thisscenario, the delay window is the provider-configured “smash and grab”time or an “abort window” per ANSI/SIA CP-01 or the like. In eitherscenario, the server-based delay time (e.g., the “smash and grab” delaytime) can be based upon user tiers (i.e., higher paying customersgetting shorter delay times) or other criteria of the provider'schoosing.

In addition, FIG. 2 illustrates a determination that a loss ofconnectivity has occurred. In an alternative embodiment, no suchdetermination need be made. Instead, if SMA controller 120 fails toprovide a disarm or some other communication to server 165 within thedelay window period, then the alarm message is provided to the centralstation.

Telephony communication module 165D provides communication between aserver 165 and telephony server 180. When a server 165 receives andperforms initial processing of alarm events, the telephony communicationmodule forwards those events to a telephony server 180 which in turncommunicates with a central station 190, as discussed above.

Integration module 165E provides infrastructure and interfaces tointegrate a server 165 with operator business systems, such as, forexample, billing, provisioning, inventory, tech support, and the like.An integration module can provide a web services interface for upstreamintegration that operator business systems can call to performoperations like creating and updating accounts and querying informationstored in a database served by database server 185. An integrationmodule can also provide an event-driven framework for downstreamintegration to inform operator business systems of events within the SMAsystem.

SMA Controller Architecture

FIG. 3A is a simplified block diagram illustrating a hardwarearchitecture of an SMA controller, according to one embodiment of thepresent invention. A processor 310 is coupled to a plurality ofcommunications transceivers, interface modules, memory modules, and userinterface modules. Processor 310, executing firmware discussed below,performs various tasks related to interpretation of alarm and non-alarmsignals received by SMA controller 120, interpreting reactions to thosesignals in light of configuration information either received from aserver (e.g., server 165) or entered into an interface provided by SMAcontroller 120 (e.g., a touch screen 320). Embodiments of the presentinvention can use a variety of processors, for example, an ARM coreprocessor such as a FREESCALE i.MX35 multimedia applications processor.

SMA controller 120 can provide for user input and display via a touchscreen 320 coupled to processor 310. Processor 310 can also provideaudio feedback to a user via use of an audio processor 325. Audioprocessor 325 can, in turn, be coupled to a speaker that provides soundin home domain 110. SMA controller 120 can be configured to provide avariety of sounds for different events detected by sensors associatedwith the SMA controller. Such sounds can be configured by a user so asto distinguish between alarm and non-alarm events.

As discussed above, an SMA controller 120 can communicate with a server165 using different network access means. Processor 310 can providebroadband access to a router (e.g., router 125) via an Ethernetbroadband connection PHY 130 or via a WiFi transceiver 335. The routercan then be coupled to or be incorporated within an appropriatebroadband modem. Cellular network connectivity can be provided by acellular transceiver 340 that is coupled to processor 310. SMAcontroller 120 can be configured with a set of rules that govern whenprocessor 310 will switch between a broadband connection and a cellularconnection to operator domain 160.

In order to communicate with the various sensors and devices within homedomain 110, processor 310 can be coupled to one or more transceivermodules via, for example, a serial peripheral interface such as a SPIbus 350. Such transceiver modules permit communication with sensors of avariety of protocols in a configurable manner. Embodiments of thepresent invention can use a transceiver to communicate with a variety ofRF sensors 130, using a variety of communication protocols. Similarly,home automation transceivers (e.g., home area network devices having anautomation interface) that communicate using, for example, Z-Wave orZigBee protocols can be coupled to processor 310 via SPI 350. If SMAcontroller 120 is coupled to a legacy security system 135, then a modulepermitting coupling to the legacy security system can be coupled toprocessor 310 via SPI 350. Other protocols can be provided for via suchplug-in modules including, for example, digital enhanced cordlesstelecommunication devices (DECT). In this manner, an SMA controller 120can be configured to provide for control of a variety of devices andprotocols known both today and in the future. In addition, processor 310can be coupled to other types of devices (e.g., transceivers orcomputers) via a universal serial bus (USB) interface 355.

In order to locally store configuration information and software (e.g.,widget programs) for SMA controller 120, a memory 360 is coupled toprocessor 310. Additional memory can be coupled to processor 310 via,for example, a secure digital interface 365. A power supply 370 is alsocoupled to processor 310 and to other devices within SMA controller 120via, for example, a power management controller module.

SMA controller 120 is configured to be a customer premises equipmentdevice that works in conjunction with server counterparts in operatordomain 160 in order to perform functions required for securitymonitoring and automation. Embodiments of SMA controller 120 provide atouch screen interface (e.g., 320) into all the SMA features. Via thevarious modules coupled to processor 310, the SMA controller bridges thesensor network, the control network, and security panel network tobroadband and cellular networks. SMA controller 120 further uses theprotocols discussed above to carry the alarm and activity events toservers in the operator domain for processing. These connections alsocarry configuration information, provisioning commands, management andreporting information, security authentication, any real-time media suchas video or audio, and any data transfer required by locally-executingwidget programs.

FIG. 3B is a simplified block diagram illustrating a logical stacking ofan SMA controller's firmware architecture, usable with embodiments ofthe present invention. Since SMA controller 120 provides securityfunctionality for home domain 110, the SMA controller should be a highlyavailable system. High availability suggests that the SMA controller beready to serve an end-user at all times, both when a user is interactingwith the SMA controller through a user interface and when alarms andother non-critical system events occur, regardless of whether a systemcomponent has failed. In order to provide such high availability, SMAcontroller 120 runs a micro-kernel operating system 370. An example of amicro-kernel operating system usable by embodiments of the presentinvention is a QNX real-time operating system. Under such a micro-kerneloperating system, drivers, applications, protocol stacks and filesystems run outside the operating system kernel in memory-protected userspace. Such a micro-kernel operating system can provide fault resiliencethrough features such as critical process monitoring and adaptivepartitioning. As a result, components can fail, including low-leveldrivers, and automatically restart without affecting other components orthe kernel and without requiring a reboot of the system. A criticalprocess monitoring feature can automatically restart failed componentsbecause those components function in the user space. An adaptivepartitioning feature of the micro kernel operating system providesguarantees of CPU resources for designated components, therebypreventing a component from consuming all CPU resources to the detrimentof other system components.

A core layer 375 of the firmware architecture provides service/eventlibrary and client API library components. A client API library canregister managers and drivers to handle events and to tell othermanagers or drivers to perform some action. The service/event librarymaintains lists of listeners for events that each manager or driverdetects and distributes according to one of the lists.

Driver layer 380 interacts with hardware peripherals of SMA controller120. For example, drivers can be provided for touch screen 320,broadband connection 330, WiFi transceiver 335, cellular transceiver340, USB interface 355, SD interface 365, audio processor 325, and thevarious modules coupled to processor 310 via SPI interface 350. Managerlayer 385 provides business and control logic used by the other layers.Managers can be provided for alarm activities, security protocols,keypad functionality, communications functionality, audio functionality,and the like.

Keypad user interface layer 390 drives the touch screen user interfaceof SMA controller 120. An example of the touch screen user interfaceconsists of a header and a footer, widget icons and underlying widgetuser interfaces. Keypad user interface layer 390 drives these userinterface elements by providing, for example, management of what thesystem Arm/Disarm interface button says and battery charge information,widget icon placement in the user face area between the header andfooter, and interacting with widget engine layer 393 to displayunderlying widget user interface when a widget icon is selected.

In embodiments of the present invention, typical SMA controllerfunctions are represented in the touch screen user interface as widgets(or active icons). Widgets provide access to the various securitymonitoring and automation control functions of SMA controller 120 aswell as support for multi-media functionality through widgets thatprovide, for example, news, sports, weather and digital picture framefunctionality. A main user interface screen can provide a set of icons,each of which represents a widget. Selection of a widget icon can thenlaunch the widget. Widget engine layer 393 includes, for example, widgetengines for native, HTML and FLASH-based widgets. Widget engines areresponsible for displaying particular widgets on the screen. Forexample, if a widget is developed in HTML, selection of such a widgetwill cause the HTML widget engine to display the selected widget ortouch screen 320. Information related to the various widgets is providedin widget layer 396.

FIG. 4 is an illustration of an example user interface for an SMAcontroller 120, according to an embodiment of the present invention. Theillustrated user interface provides a set of widget icons 410 thatprovide access to functionality of SMA controller 120. As illustrated,widgets are provided to access security functionality, camera images,thermostat control, lighting control, and other settings of the SMAcontroller. Additional widgets are provided to access network-basedinformation such as weather, news, traffic, and digital picture framefunctionality. A header 420 provides access to an Arm/Disarm button 425that allows for arming the security system or disarming it. Additionalinformation can be provided in the header, such as, for example, networkstatus messages. A footer 430 can provide additional status informationsuch as time and date, as displayed.

A user can select widgets corresponding to desired functionality.Embodiments of the present invention provide for access to widgets viaportal server 170. A provider of operator domain 160 can determinefunctionality accessible to users, either for all users or based upontiers of users (e.g., subscription levels associated with paymentlevels). A user can then select from the set of accessible widgets andthe selected widgets will be distributed and displayed on the userinterface of SMA controller 120. Configurability of SMA controller 120is also driven by user determined actions and reactions to sensorstimulus.

Computer system 510 includes a bus 512 which interconnects majorsubsystems of computer system 510, such as a central processor 514, asystem memory 517 (typically RAM, but which may also include ROM, FLASHRAM, or the like), an input/output controller 518, an external audiodevice, such as a speaker system 520 via an audio output interface 522,an external device, such as a display screen 524 via display adapter526, serial ports 528 and 530, a keyboard 532 (interfaced with akeyboard controller 533), a storage interface 534, a floppy disk drive537 operative to receive a floppy disk 538, a host bus adapter (HBA)interface card 535A operative to connect with a Fibre Channel network590, a host bus adapter (HBA) interface card 535B operative to connectto a SCSI bus 539, and an optical disk drive 540 operative to receive anoptical disk 542. Also included are a mouse 546 (or otherpoint-and-click device, coupled to bus 512 via serial port 528), a modem547 (coupled to bus 512 via serial port 530), and a network interface548 (coupled directly to bus 512).

Bus 512 allows data communication between central processor 514 andsystem memory 517, which may include read-only memory (ROM) or FLASHmemory (neither shown), and random access memory (RAM) (not shown), aspreviously noted. The RAM is generally the main memory into which theoperating system and application programs are loaded. The ROM or FLASHmemory can contain, among other code, the Basic Input-Output system(BIOS) which controls basic hardware operation such as the interactionwith peripheral components. Applications resident with computer system510 are generally stored on and accessed via a computer-readable medium,such as a hard disk drive (e.g., fixed disk 544), an optical drive(e.g., optical drive 540), a floppy disk unit 537, or other storagemedium. Additionally, applications can be in the form of electronicsignals modulated in accordance with the application and datacommunication technology when accessed via network modem 547 orinterface 548.

Storage interface 534, as with the other storage interfaces of computersystem 510, can connect to a standard computer-readable medium forstorage and/or retrieval of information, such as a fixed disk drive 544.Fixed disk drive 544 may be a part of computer system 510 or may beseparate and accessed through other interface systems. Modem 547 mayprovide a direct connection to a remote server via a telephone link orto the Internet via an internet service provider (ISP). Networkinterface 548 may provide a direct connection to a remote server via adirect network link to the Internet via a POP (point of presence).Network interface 548 may provide such connection using wirelesstechniques, including digital cellular telephone connection, CellularDigital Packet Data (CDPD) connection, digital satellite data connectionor the like.

Many other devices or subsystems (not shown) may be connected in asimilar manner (e.g., document scanners, digital cameras and so on).Conversely, all of the devices shown in FIG. 5 need not be present topractice the present invention. The devices and subsystems can beinterconnected in different ways from that shown in FIG. 5. Theoperation of a computer system such as that shown in FIG. 5 is readilyknown in the art and is not discussed in detail in this application.Code to implement the present invention can be stored incomputer-readable storage media such as one or more of system memory517, fixed disk 544, optical disk 542, or floppy disk 538. The operatingsystem provided on computer system 510 may be MS-DOS®, MS-WINDOWS®,OS/2®, UNIX®, Linux®, or another known operating system.

Moreover, regarding the signals described herein, those skilled in theart will recognize that a signal can be directly transmitted from afirst block to a second block, or a signal can be modified (e.g.,amplified, attenuated, delayed, latched, buffered, inverted, filtered,or otherwise modified) between the blocks. Although the signals of theabove described embodiment are characterized as transmitted from oneblock to the next, other embodiments of the present invention mayinclude modified signals in place of such directly transmitted signalsas long as the informational and/or functional aspect of the signal istransmitted between blocks. To some extent, a signal input at a secondblock can be conceptualized as a second signal derived from a firstsignal output from a first block due to physical limitations of thecircuitry involved (e.g., there will inevitably be some attenuation anddelay). Therefore, as used herein, a second signal derived from a firstsignal includes the first signal or any modifications to the firstsignal, whether due to circuit limitations or due to passage throughother circuit elements which do not change the informational and/orfinal functional aspect of the first signal.

FIG. 6 is a block diagram depicting a network architecture 600 in whichclient systems 610, 620 and 630, as well as storage servers 640A and640B (any of which can be implemented using computer system 510), arecoupled to a network 650. Storage server 640A is further depicted ashaving storage devices 660A(1)-(N) directly attached, and storage server640B is depicted with storage devices 660B(1)-(N) directly attached.Storage servers 640A and 640B are also connected to a SAN fabric 670,although connection to a storage area network is not required foroperation of the invention. SAN fabric 670 supports access to storagedevices 680(1)-(N) by storage servers 640A and 640B, and so by clientsystems 610, 620 and 630 via network 650. Intelligent storage array 690is also shown as an example of a specific storage device accessible viaSAN fabric 670.

With reference to computer system 510, modem 547, network interface 548or some other method can be used to provide connectivity from each ofclient computer systems 610, 620 and 630 to network 650. Client systems610, 620 and 630 are able to access information on storage server 640Aor 640B using, for example, a web browser or other client software (notshown). Such a client allows client systems 610, 620 and 630 to accessdata hosted by storage server 640A or 640B or one of storage devices660A(1)-(N), 660B(1)-(N), 680(1)-(N) or intelligent storage array 690.FIG. 6 depicts the use of a network such as the Internet for exchangingdata, but the present invention is not limited to the Internet or anyparticular network-based environment.
